DNSTOOL README
PURPOSE
Dnstool is a set of curses-based user interfaces and supporting scripts
for easy administration of some dns zones with dozens of reverse zones.
LICENSE
Dnstool is distributed under the terms of the GNU General Public License
(GPL) version 3 or later (at your option), which can be found in the file
named COPYING.
INSTALLING
Prerequisites:
Debian/Ubuntu "DNS Server" base install
# apt-get install libnetaddr-ip-perl libnet-dns-perl libcurses-perl libcurses-ui-perl
Assumes a Debian-style BIND version 9 install; should be adaptable to other
layouts, previous incarnations have been known to run fine on RHEL.
Configuration is saved in DNS, in the "policy.dnstool" and "networks.dnstool"
local zones.
For an example setup using RFC 5737 networks, do a "make install", then add
include "/etc/bind/named.conf.dnstool";
include "/etc/bind/named.conf.example";
to /etc/bind/named.conf and do your usual "rndc reconfig" incantation.
The toolmaster configured in "policy.dnstool" needs to be correct in the local
DNS, or nothing will work. An otherwise-working /etc/hosts override is not enough.
The example zone has the toolmaster at 192.0.2.5.
/etc/bind/dnstool/empty-zone is the template for new reverse zones, edit to suit.
Config layout: (/var files are updated by scripts or named, /etc is left to the sysadmin)

RUNNING
The individual tools should be pretty self-explanatory.
Meant to be run on a DNS master, as the BIND user.
dnstool edits forward and reverse zones.
dnstool-admin edits the list of administered reverse zones.
In case of trouble, the tools log to $HOME/dnstool.log
respective $HOME/dnstool-admin.log.
dnstool-zonesync is a helper script that creates the actual reverse zones and reloads bind config.
extras/ has various other scripts useful for automation and documentation.
